Use the amount of peanut butter that reaches your toast, sandwich, or bowl. A level tablespoon and a heaped spoonful are different amounts, so grams help when the spoon is hard to judge.
A worked portion example
Illustrative calculation: 2 tablespoons weighs 32 g using the linked record's portion weight × 2. At 598 calories per 100 g, 32 × 598 ÷ 100 = about 191 calories and 7.1 g protein. The two source-sized tablespoons total 32 g. Bread, jelly, and other foods are outside this calculation.
Check the exact food and household measure →The regular peanut-butter entry lists one tablespoon as 16 g. Two of those tablespoons are 32 g. For a generous spoonful, use its actual weight rather than automatically calling it one tablespoon; the package may also show a different serving size.
Regular, reduced-fat, lower-sugar, and lower-sodium peanut butter have separate examples. Those descriptions do not tell you the exact nutrition of every brand. Check the product label, including the grams per serving, before scaling it to your spoonful.
If you spread peanut butter on both slices, add the amounts from both sides. Bread, jelly, banana, and other fillings are separate from this peanut-butter calculation. For a sauce blended with peanut butter, use the whole sauce recipe and the portion served.
Editorial update: . Portion examples are calculations from the linked USDA records.
The 6 exact records in this guide report 166–208 calories in the records' own listed source servings and 520–650 calories per 100 grams. Those are observations from named database records—not a universal range or an estimate of an unseen plate.
Across all 6 named USDA examples, a tablespoon contains 83–104 calories. Each included example lists 16 g for that measure. The same household label can carry a different gram weight elsewhere in USDA data.
Match my meal
For Peanut butter, begin by separating “Peanut butter” from “Peanut butter, vitamin and mineral fortified.” Choosing a card filters this source set; it does not infer the portion or fill in ingredients the chosen description does not name.

What this page compares
This guide keeps 6 named USDA records in view: 6 direct matches. All sit within “Nuts and seeds.” The exact descriptions remain the unit of comparison; the familiar heading is only the doorway into the evidence.
Why these records appear together: The deterministic grouping rule “normalized first description segment” placed these 6 records together under the exact grouping key “peanut butter.” That rule determines membership before any nutrition result is read.
For Peanut butter, this page can compare 6 named records from FDC 2707537 through FDC 2707542. It cannot observe which preparation was eaten, recover unnamed additions, or supply the eaten grams.

Editor’s decision brief
Carry the denominator, exact identity, and strongest observed contrast into every number below.
Portion
Equal source weights make the selected Peanut butter serving totals easier to compare, but the eaten portion still has to be measured or estimated.
Composition
The lower endpoint is “reduced fat”; the higher is “lower sugar.” This isolates density, not ingredient causation.
Discriminator
Of protein, fiber, and sodium, the strongest normalized contrast is between “lower sodium” (17 mg) and “reduced fat” (540 mg).
Observed source examples
These 6 records each use a 32 g serving. Their serving calories compare equal weights within this set. They do not define a calorie range for every peanut butter; match the preparation and adjust to your portion.

Full comparison
For Peanut butter, serving columns preserve each record’s own listed amount, while calories per 100 g hold weight constant. A dash means the cited record does not supply that field; it does not mean the nutrient is absent.

Portion analysis
Every selected record uses a 32-gram source amount, so serving-weight differences do not explain the calorie spread inside this set. Their own source servings run from 166 calories for “reduced fat” to 208 for “lower sugar.” At a fixed 100 grams, “reduced fat” is 520 calories and “lower sugar” is 650—a fixed-weight separation of 130 calories. For Peanut butter, the serving view answers “how much is in the database portion?”; the 100-gram view answers “how concentrated is the matched record?” Neither reveals how many grams were actually eaten.
The scaling rule: multiply a per-100-gram value by eaten grams ÷ 100. The arithmetic is exact; the result is only as defensible as the record match and portion estimate.
Preparation analysis
The published descriptions distinguish forms such as “Peanut butter”, “lower sodium”, “lower sugar”, “reduced fat”, and “vitamin and mineral fortified”. The source formulations contain 5 distinct ingredient codes; examples that appear in only part of the set include peanut butter, smooth style, without salt, peanut spread, reduced sugar, peanut butter, smooth style, with salt (includes foods for usda's food distribution program), and peanut butter, smooth, reduced fat. On this Peanut butter page, those rows make the records inspectable, but they are not a controlled experiment: they cannot tell us that one named input, by itself, caused a nutrient difference.
Database precision is not meal certainty. Retain the exact description beside the number so later corrections remain possible.
What changes the comparison
The family label “Peanut butter” cannot resolve the differences between Peanut butter and Peanut butter, vitamin and mineral fortified. The four checks below identify the record wording, source weight, and formulation evidence that can.
Every selected record uses 32 grams. Inside this set, serving-calorie differences therefore reflect the published composition rather than a change in source weight.
Representative record-level distinctions include “Peanut butter”, “lower sodium”, “lower sugar”, “reduced fat”, and “vitamin and mineral fortified”. Those phrases are evidence for choosing a record, not decorative subtitle text.
5 source-input codes appear across the selected records. Their presence and listed weights describe USDA formulations, not finished plated proportions.
Even “Peanut butter” leaves the eaten grams and unnamed oils, sauces, toppings, substitutions, or leftovers unresolved. Preserve those Peanut butter unknowns for correction instead of converting them into false precision.
Record matching
Read the source name as a sequence of decisions. First confirm that peanut butter is the right meal family. Then resolve the phrases that actually separate this set—“Peanut butter”, “lower sodium and lower sugar”, “lower sugar”, and “vitamin and mineral fortified”—before comparing gram weight. If a package, menu, or known recipe provides a closer first-party description, prefer it and keep this USDA record as a transparent fallback.
Decision support from the exact records on this page
These conclusions and reading paths are computed from 6 exact records behind Peanut butter source-record guide. Links are chosen by record identity, controlled contrast, formulation input, nutrient spread, or serving context—not by loose keyword similarity.
Equal-weight result
Peanut butter, reduced fat reports 540 mg versus 17 mg for Peanut butter, lower sodium: a 523 mg difference when both are normalized to 100 g.
Inspect the underlying evidenceThese listed servings have equal weights
The 6 records with a listed serving weight on this page each use 32 g. Their serving totals therefore compare equal weights, even if the household labels differ. Match the preparation and adjust the weight to the amount you eat.
Choose the record before reading the number
The page keeps both records at the same 100 g denominator and makes Fat-level wording (No matching controlled term in the source name versus reduced-fat wording) the explicit record-description contrast. It does not show that the wording difference caused a nutrient difference. Pick the description that matches the food in front of you rather than averaging away the distinction.
Inspect the underlying evidenceContextual knowledge graph
For Peanut butter source-record guide, each path states why the destination belongs here, so you can distinguish a true evidentiary connection from a merely similar label.
Both records appear in this page’s evidence set. The explicit record-description contrast is Fat-level wording: No matching controlled term in the source name versus reduced-fat wording; it is a selection cue, not evidence of cause.
